7 total objects seen in the sky coming from the vicinity of the ocean, triangular orange lights that seemed to pulsate, stop and hover

My Co-worker and I were on top of a parking deck talking and she saw the first one come off the ocean and hover, I looked up to see a triangular orange light that seemed to be pulsating and at a stand still. It was close enough that had it been an aircraft we should have heard some type of noise, yet we did not.

Then 2 more came from the vicinity of the ocean and hovered with the first. They then appeared to be getting smaller and we could tell that they were actually getting farther away from us. Then they disappeared.

We were in shock and were talking about what we had just witnessed when two more in the same formation as the two that came in together before came in, stopped and hovered, then again started to ascend until they disappeared.

My husband came up and we were telling him what we had seen when a single object appeared coming from the ocean and it too hovered then started to ascend. We talked for a couple of minutes then went upstairs into our of! fice. I walked to the window to look one more time and another single object was in the sky in the same space as the others, I knocked on the window to get my husband's attention and pointed to it, and he too saw that one and we watched it until it disappeared like the others.
